HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 265,418, dated October3, 1882.

Application filed February 25, 1882.

To all whom at may concern:

Be it known that 1, WILLIAM G. HOWELL, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented an Improvement inthe Manufacture of Horseshoes, of which the following is aspecification.

My invention has reference to horseshoes made from compound bars of ironand steel; and it consists in forming a horseshoe of combined iron andsteel byinclosing a bar of steel of substantially diamond shape orsquare in cross-section within two arch-shaped or channel bars of softiron, the edges of said steel bar coinciding with that part of thearch-shaped pieces as would correspond with the spring and crown, andthe pile thus formed is brought to awelding heat and run through rollsand rolled ontinto horseshoe-bars and formed into horseshoes in whichthe toe-call; and the heelcalks shall have an edge of steel on theirwearing-surface, and that part.ot' the bar which is grooved or creasedfor the reception of the nails will be mainly through the sot'tiron, andthe weld between the iron and steel almost at right angles to saidcrease,all of which-is more fully set forth in the followingspecification and shown in the accompanying drawings, which form partthereof.

Heretofore in making horscshoes it has been customary to pile the steeland iron so as to make welds in line with the crease; but this isobjectionable, as in forming the said creases the steel is liable to beseparated from the iron, and in some instances there was a layer of softiron upon the toe and heel calks, and in other cases, after the pile hasbeen rolledinto horseshoebars, the creases have to be made through thesteel.

The objectof my invention is to construct horseshoes the calks of whichwill have a steel edge in the middle and incased on each side with softiron, and in which the creases will be formed, to a very great extent,through soft iron, but through suificient of the steel to give (Nomodel.)

3 and 4 are cross-sections of same, respectively. on lines 2 z and y y.Fig. 5 is an end view of a pile as made by one of the methods heretoforeused, and Fig. 6 is a plan view of my improved horseshoe.

A is a steel bar of substantially a diamond or square shape in crosssection, its sides being preferably curved, as shown. Inclosing thissteel bar are two bars of sot't iron, 13 B, their edges meeting on aline with two of the edges of the steel baron diametrically-oppositesides, and, as shown at O G, the said bars A and B B, when arranged asabove, forming a square or rectanglein crosssection. From this it willbe seen that the edges of the steel are only covered with a thin layerof soft iron, while the sides thereof are covered with substantiallytriangular bars of metal, two of said triangular bars being formedtogether to make a bar, B. The edge 1) of the steel bar will correspondto the calk when the pile is rolled out into horseshoe-bars,and thelinezz will correspond to the creases. After being brought to a weldingheat the pile is passed through suitable reducing and forming rolls,which weld the iron bars 15 B to the steel bar A, the joints 0 Gbecoming obliterated, and the steel edges 1), &c., are broughtpractically to the surface, as shown in Figs. 3 and L.

E represents the horseshoe-bar, in which G are the calks, and F thecreases. It will be seen by examining Fig.3 that the crease F is,

to a very great extent, throught soft iron, but is partly through thesteel-edge G, and the welds are across the creases; and in Fig.4 it willbe seen that the calk G is made up of the steel edge D, inclosed on eachside with soft metal. As the iron wears away the edge of the steelbecomes more prominent, and is adapted to withstand great wear andimpart great strength to the calk and the entire shoe, preventing easywear, even upon the body of the shoe, as in the case of the calks. Thisform of pile, though particularly adapted to shoes having calks, is alsoadapted to shoes having no calks or toe-calks alone.

In this application I do not claim the general construction of makingpiles of combined iron and steel of shapes having but two joints in thepuddle-bars which inclose the steel, and when placed together forming astable pile, or

ter of diamond shape, the edges eorrespond- :5 ing" with the sides ofthe shoe, said steel being wholly inclosed in iron, to which it iswelded, and the creases for the nails being formed mainly through theiron, but also through one edge of the steel, substantially as shown anddescribed.

In testimony of which invention I hereunto set my hand this 23d day ofFebruary, A. 1). 1882.
